Lazy number range generator
Useful for iteration.
Similar to the Python 3 range function.
$ npm install get-range
const getRange = require('get-range');
for (const index of getRange({end: 4})) {
console.log(index);
}
//=> 0
//=> 1
//=> 2
//=> 3
const range = getRange({start: 0, end: 4, step: 2});
range.next().value;
//=> 0
range.next().value;
//=> 2
console.log(...getRange({start: 0, end: -5, step: -1}));
//=> [0, -1, -2, -3, -4]
Can replace for-loops in many cases:
// Before
for (let i = 0; i < 5; i++) {}
// After
for (const i of getRange({end: 5})) {}
Returns a Generator object (which is both an Iterable and Iterator).
